GAS GENERATOR AND BURNER.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed August 1, 1916. Serial No. 112,508.

To all whom it may concern Be it known that I, GEORGE L. N. J GEN- son,citizen of the United States, residing at lVatsonville, county of Santa Cruz, State of California, have invented certain new and useful Improvements in Gas Generators and Burners, whereof the following is a specifi- .cation.

This invention relates to gas generators and burners. It more especially relates to apparatus which converts a liquid fuel intov a gas and burns the gas, and in which a portion of the heat of the burning gas is depended upon to gasify a further portion of the liquid.

In the accompanying one sheet of drawing I have illustrated an apparatus containing my invention in the best form as yet devised by me. In the apparatus shown in the drawing the oil is fed by gravity, or other pressure, into a vaporizer which is in the form of an oblong ring. In this ring, the oil enters a channel which passes around the ring and is provided with outlets through which a portion of the oil exudes onto a bit of waste or other substance, where, being ignited, it heats the ring, andvaporizes the oil therein. When the ring is sufiiciently hot to continuously vaporize the oil entering it, the first named channel is connected, by the turning of a suitable valve, with a channel of larger caliber, also extending around the ring, where the vaporization is completed. The vapor thus formed is exuded through suitable orifices and burns, thus giving the heat desired. Various details of the apparatus will appear and be fully described in the description which now follows, in connection with the drawing.

In the drawing :Figure 1 is an elevation of the apparatus, partly in section at one end, to better show the interior construction; said section being taken on line 1, 1, of Fig. 2.

Fig. 2 is a cross section taken at the line 2, 2, of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a section upon the line 3, 3, of Fig. 1 looking in the direction of the arrow.

Fig. 4 is a section upon the line 4, 4, of Fig.

Fig. 5 is a top view of the needle valve gage. This valve controls the feed of 011 to the ring.

In these figures :1 and 2 are bridge castings, which, at their ends, are bolted together through blocks 3 and 4, all of which together constitute the generator and burner. The bolts 5 may pass through flanges on the members 1 and 2, and through flanges or inert parts of the blocks 3 and 4. In making the castings, which may be of iron, the molten metal is run around copper tubes 6 and 7, placed in the molds, so that the channels hereinafter to be described, may be lined throughout with copper.

The feed pipe 8 may be applied to the member 1, at any convenient point, as at the end as shown, or at one side, as at the boss 9, or elsewhere. Included in the course of the .feed pipe 8, is a needle valve 10 for controlling the flow of oil into the device, and the oil may further pass through a sight feed or other device to indicate its flow, or non-flow. Such device, as also the needle valve and its gage, shown in Fig. 5, need not be further described as their construction and application will be obvious to any mechanic from the above.

The block 3 is a plain block for connecting purposes, and might be omitted by a suitable conformation of the members 1 and 2. The block is perforated by holes 11, see more particularly Fig. 4, which connect the channels in member 1 with those in member 2.

Block 4 is similar to block 3, but the holes 12 in it are turned in, like a letter X, to a central bore, in which is arranged a plug 13, the whole constituting a plug valve or cook. The by-pass in the plug is at one side, so that the cock is a fourway cock, as clearly shown in Fig. 3, the purpose of which will presently appear. If desired, the plug 13 may be operated by a key 15, instead of a handle, thus insuring against tampering with the device.

16 represents the front wall of a stove or furnace or whatever heating arrangement the apparatus is applied to.

In operation, oil fed in through pipe 8, enters channel 17, in member 1, and from it passes through the holes 11 and 12, into the corresponding channel 18, in member 2, whence a portion of it exudes through the nozzles 19, and is ignited, and, by its burning, heats the apparatus. The apparatus be ing heated to the point required to vaporize the oil, or whatever liquid fuel is used, the fourway cock 13 is turned to connect the 7 desired. The vapor channels Q0 and 21 are of larger caliber than the oil channels 17 and 18, to accoi'nnlodate the greater volume or the vapor, and so prevent an undue pres- Having thus described my invention, and an embodiment of it, in the full, clear and exact terms required by law, and knowing that it comprises novel, useful and valuable improvements in the art to v: iich it pertains, I here state that 1 do not Wish to be limited to the precise construction and arrangement of the several parts, as herein set forth, as the same may be variously modified by a skilled mechanic Without departing from the spirit of the invention. 7

What I claim and desire to secure by Letters Patent of the United States, is the i'ol lowing, to Wit passages to said channels, said vapor channel being provided With burner nozzles adapted to direct a flame against the ring to heat the same.

in testimony that I claim the fore 'oing I have hereto set my hand in'the presence of two Witnesses, this 27th day of July, 1916.
